COTTON-CHOPPER.

. following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to certain new and useful improvements in cottonchoppers, the object of the invention being to provide an efficient andpractical device of this character, whereby the construction thereof isconsiderably simplified, and having novel means whereby the cultivatorblades may be raised more at one end than at the other, or they may beraised altogether, and upon an equal horizontal plane, thus regulatingthe depth of the blades into the soil.

A further object of the invention is to provide a device of this design,havin a special form of rotar cutter, for severing t e cotton,consisting o a disk, having a plurality of knife-carrying members, whichare adjustable radially from the center thereof.

This invention com rises further objects and combinations of e ementswhich will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claims.

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and advantages,reference is to be had to the hereinafter set forth description and theaccom anying drawings in connection therewith, w erein Figure 1 is avertical longitudinal sectional view through the cotton chopper. Fig. 2is a to plan view thereof. Fig. 3 is a rear view of tlie device to showclearly the rack for adjustably holding the shaft of the cultivatorblades. Fig. 4 is a detail sectional view on line 44 of Fig. 1, showingthe swivel joint and the ivot of the lever for shiftin the cultivatorlades. Fig. 5 is a sectional view on line 5-5 of Fig. 1, to show moreclearly the rotary cutter. Fig. 6 is a detail view of the frame forsupporting the cultivator blades.

Making renewed reference to the accompanying drawings, wherein similarreference characters indicate corresponding parts in the severalillustrations, by figures, 1 desig- Hates the frame of the device, inwhich is l Specification of Letters Patent.

j ournaled the main drive shaft 2, upon which. the drive wheels 3 arejournaled, and also mounted thereon is a bevel gear 4, which is in meshwith a similar beveled gear 5, which is mounted upon a'secondary shaft6, extending at right angles to the shaft 2, to which is fixed therotary cutter 7, consisting of a disk 8, having a plurality ofknife-carrying members 9, to which are fixed the cutting knives 1O saidknife-carrying members are. adjustable by means of socket members 1 1,having thumb screws 12, mounted therein for the purpose of engaging therecesses 13 in said rnife-carrying members, renderin them adjustableradially with relation to t e disk, as clearly shown in Fig. 5 of thedrawings.

The cotton chopper is provided with a plurality of cultivator blades 14,having a body portion 15 thereof, which are pivoted upon a shaft 16,journaled within the frame of the apparatus; the cultivator blades areraised 'more at one end than at the other, or are raised altogether,upon an equal horizontal plane, by means of a loosely jointed frame 17,which. is connected with a body portion of the cultivator blades, bychains 18; the upper rod 19 of the loosely jointed frame 17 is providedwith a sleeve 20, which is slidably mounted thereon, and provided withan upwardly extending arm 21, which is pivoted to an oscillating lever22, as shown in Fig. 1 of the drawings. This oscillating lever ispivoted to a stud 23, which is connected to a longitudinal beam 24, bymeans of a swiveled joint 25; this longitudinal beam forms a part of theframe of the apparatus, and is secured, as at 26, to the arched braces27, for the purpose of bracing the complete frame of the apparatus, aswill be clearly observed.

Fixed to this longitudinal beam, as at 28,

is a rack 29, for securely holding the oscillating lever in adjustedposition; springs 30 are provided for cooperation in conjunction withsaid oscillating lever, to prevent displacement thereof, when adjusted,as will be understood.

Suitable handles 31 are provided, which are fixed to the frame of theapparatus, as at 32, and projecting downwardly from the frame, arecultivator blades 33, as shown in Fig. 1 of the drawings.

Projecting from the front of the frame 1 is a semi-circular loop 34,having an eye 35, to which an evener 36 is connected, as clearly shownin the drawings.

It is to be understood that various changes in the minor details ofconstruction may be made, such as the adjustable feature of the knivesof the rotary cutter, the loosely jointed frame for supporting thecultivator blades, and other features without departing from the spiritof the invention, with. the understanding that such changes, as will benecessary, will be embraced within the scope of the appended claims.

From the foregoing, the essential features, elements and operation ofthe device, together with the simplicity and practicability thereof willbe clearly observed, and, when, manufactured in accordance with theinvention, an inexpensive market will be easily obtained therefor.

Having thus fully described the invention, What is claimed as new anduseful by the protection of Letters Patent is 1. In a cotton cultivator,the combination of a frame; a drive shaft journaled therein; drivingwheels therefor; a plurality of cultivator blades pivoted to the frame;a lever pivoted and swiveled to the frame and provided with a link atone end, having a sleeve; a flexible frame, a portion of which beingslidable in said. sleeve and provided with chain connections with thecultivator blades; a plurality of racks for holding said lever 111adjusted position as and for the purpose specifically set forth.

2. In a cotton cultivator, the conlbination of a frame; a drive shaftjournaled therein; driving wheels therefor; a plurality of cultivatorblades pivoted to the frame; a lever pivoted and swiveled to the frame,and provided with a link at one end, having a sleeve; a flexible frame,a portion of which, being slidable in said sleeve and provided withchain connections with the eultivalor blades; plurality of racks forholding said lever in adjusted position for the purpose specifically setforth, and a revolving cutter having gear connections with the saiddrive shaft as and for the purpose specifically set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
